The Ethereum Foundation has announced the Trillion Dollar Security (1TS) initiative aimed at enhancing the security of the Ethereum network. The goal of the initiative is to ensure the safe storage of large amounts of money on the Ethereum network, so that billions of users can safely store over $1,000, and companies can safely operate up to $1 trillion in a single application or smart contract. The initiative includes assessing vulnerabilities, making improvements, and informing about progress.
